Installation pre-requisites failure - not reading php.ini

[MarkR]

Zabbix: 1.8.11
Centos 6.2 (64-bt)
PHP: 5.3.3
Apache: 2.2.15

I'm new to Zabbix, first time installation. The prerequisites check is failing of the following php configurations:
post_max_size
max_execution_size
max_input_time
timezone.

I have corrected these setting in /etc/php.ini however it appears the settings/or file are not being read. I have searched for other copies of php.ini and can find none. /etc/php.ini is the only copy.
phpinfo(); confirms the etc/php.ini is the loaded configuration file.

Any help/suggestions would be greatly appreciated.

Thanks,
Mark.

php -i|grep php.ini revealed a syntax error in the file.

Working now.
